Resumo:
The woods used in structures in Brazilian Northeast Region are from of Amazon
Region. The present work aimed evaluates the natural resistance of seven woods of Amazonian to
subterranean termites under alimentary preference assay. The studied woods were Myroxylon
balsamum, Simarouba amara, Lantana camera, Guarea sp., Amburana acreana, Micrandropsis
scloroxylon and Ceiba pentandra. Test samples measuring 10.16 x 2.00 x 0.64 cm, with larger
dimension in the fiber direction were obtained. The woods were submitted to Nasutitermes corniger
action by 45 days. The M. balsamum presented larger resistance and the C. pentandra the least one,
having been completely consumed by termites. There was not significant relationship between density
and the mass loss to studied species.
